A very good tool
A tool whose price is a definite obstacle for any buyer. However, the ergonomics, the fluidity, the pain in the forearms that disappear, make you forget this handicap. Intensive users are the first to be affected; hand injuries are not just a figment of the imagination. When they do occur, the consequences of these disruptions to daily life, which had not been envisaged ("it's all talk / it won't happen to me / we're not made of sugar"), are surprisingly far-reaching. So for intensive users, it's good to anticipate health problems; for others, given the price: it's too expensive.
